Unsaturated carboxylic acid esters having a 2E,4E stereoconfiguration (wherein X stands for hydrogen, C1-4 alkoxy or hydroxy and R represents C1-4 alkyl), may be prepared by reacting a salt (wherein M stands for a metal ion or an ammonium ion substituted by one or more alkyl and/or aralkyl group(s) and X has the same meaning as stated above) with an alkyl halide R-Y (where...

An apparatus serves for the palletisation of stacks (30) lying next to one another and composed of flat articles, preferably bags, in a plurality of layers. The stacks of successive layers are preferably arranged offset relative to one another. The apparatus possesses a table plate (27) which carries the pallet (29) and which can be raised and lowered. So that stable pallet stacks can be formed in...

A process for the preparation of a C(3)-C(4)-transconfigurated gamma -butyrolactam of the formula (I) (I) in which R1 represents hydrogen or alkyl, aryl or aralkyl with in each case up to 10 carbon atoms and R2 and R3 are identical or different and represent hydrogen, alkyl, aryl, aralkyl, alkoxy, aryloxy or aralkoxy with in each case up to 10 carbon atoms, acyl with up to 18 carbon a...

Sequencing of the XPR2 and LEU2 genes of Yarrowia lipolytica, recombinant Yarrowia lipolytica cloning vehicles comprising heterologous DNA coding for the expression of mammalian protein and other polypeptides, including plasmids suited for transformation of Y. lipolytica hosts and incorporating a regulon homologous to the host in its untransformed state, and secretion signals for the heterologous ...

Strains of Acetobacter that are stable agitated culture conditions are claimed as well as a unique reticulated cellulose product, and a method and media for producing such bacterial cellulose under agitated culture conditions. Sustained production of bacterial cellulose over an average of 70 hours of at least 0.1 g/liter per hour is achieved. Further, sheets comprising the microbially produced cel...

Chiral diphosphinerhodium complexes of the formula in which X, Y and L are as defined in Claim 1 and their preparation are described.

A fuel assembly has a bundle of elongated fuel rods disposed in a side-by-side relationship so as to form an array of spaced fuel rods, an outer tubular flow channel surrounding the fuel rods so as to direct flow of coolant/moderator fluid along the fuel rods, a hollow water cross extending centrally through and interconnected with the outer flow channel so as to divide the channel into separate c...

The absorbents (1) are fitted on the base with the aid of a number of wire-form holders (2) which have a first arm (3,4) on the under side of the absorbent, and a second (6,7) on the top side of it. The second arm has a part (8,9) extending towards the base with components (11) which work in conjunction with a fixture for holding it against the base.

The bars (5) are fixed at their lower ends to a metal plate (7). This plate has a central opening (8) which accommodates and supports the lower end of the basket (3) resting on the frame (1).

The sealing ring is for use between two radial faces on components on a shaft holding them together and allowing them to turn in relation to each other. It comprises a holder (9) on which a first sealing face (15) is formed, and a body (10) with a sealing edge (16) forming the opposite component. The body is secured by a joint (11) to the holder, so that it can assume an essentially stable positio...

Illumination of objects, partic. at sea, takes place repeatedly on an intermittent basis, using a rotating ultra-violet light source which sweeps around the complete horizon. The source speed of rotation is adjusted either so that the reflected light appears to be blinking to an observer, or is continuous. Light from the source, prior to transmission, is made to pass through a medium, such as glas...

At least one ultra-violet light source is incorporated on the mast of the vessel, and the light it radiates passes through a glass or corresp. in which visible light is to a large extent absorbed. The light from the source is mainly in the wavelength range of 360-370 nm. A piston, tube or similar capsule formation is arranged around the light source lamp in order to achieve even light diffusion, a...

The melting conductor (2) is in series with the conductor between blade cartridge contacts, and pref. is of short extent in the longitudinal direction of the cartridge. Inside the melting conductor is a connecting and protection plate (3) with a female part for connection to a current rail (7) male part. When these two parts are connected, the rail conducts current from the right contact (1) to th...

A folding saw comprises a long arm 10 and a short arm 11 which are pivotably connected and can be pivoted out to a set position. In the folded-out position, a saw blade 25 is secured between the arms. At the outer end of the long arm this is connected to the end of the saw blade by a link 28, which in the usage position of the saw forms a bracket arm projecting preferably at right-angles from the ...

The invention relates to apparatus for manipulating small quantities of liquid, comprising at least one test tube for accommodating the quantity of liquid, a cannula which can be inserted into the vessel, and a control arrangement for controlling the system vessel and cannula in relation to one another in a manner such as to bring the cannula to the bottom of the vessel. In accordance with the inv...
